Define what a CMM is
A coordinate Measuring Machine, also recognized as a CMM, is a piece of apparatus that measures the dimensions of geometrical objects. CMMs use a very sensitive probing system to make contact with points on the surfaces of geometrical objects. A stylus (plural: styli) is the “tip” attached to the probing system on a coordinate measuring machine.
.
History of the CMM.
The first CMM was built by the Ferranti Company of Scotland around 1950s.
There was a need to measure precision mechanisms in the military products this company fabricated. This machine only had only 2 axes.
Types of most CMMs.
Manufactures offer four elementary types of coordinate measuring machines that offer specific benefits depending on the mechanisms being measured.
- Bridge type
- Cantilever type
- Gantry type
- Horizontal arm type
Describe some types of software used in CMMs.
- PC-DMIS CMM is one the world's leading coordinate measurement machine (CMM) Software.
- Mitutoyo MCOSMOS 2D and 3D coordinate measuring machine software helps achieve measuring activities rapidly and simply. MCOSMOS software is easy to operate from entry level to experts.
- Zeiss CALYPSO measures geometrical components simply, rapidly and dependably.
Discuss the use of coordinate measurement machines in the industry.
CMMs have been used in many industries to measure components of all forms and dimensions. Widely used for inspecting parts in automotive, aerospace, aviation, and in medical and biotechnology fields. Coordinate Measuring Machines are indispensable for guaranteeing reliable, precise dimensions in order to comply with ISO requirements.
